Comfort and Convenience
Cabin temperature is a common point of difference: what feels pleasant to a driver in a jacket can feel stuffy to someone in the back. Preferences vary with clothing, seating position and personal sensitivity.
Safety and Driver Assistance
Spending a moment with lights, wipers, mirrors and hazard switches before setting off means fewer unfamiliar searches later. Preparation while parked lets attention stay with driving once passengers are aboard and conversation begins.
Multimedia and Connectivity
Phone battery drains quickly when navigation runs for a whole journey. Where a charging socket is available, deciding early who uses it saves passengers passing a cable back and forth once the car is moving.
